Abstract
A method for processing at least an imprint image of an individual using a processing device that comprises an exhibition glass sheet having a surface for receiving said imprint. The method includes acquiring without contact at least one image of the imprint present in the space upstream from the said surface and which has not yet been in contact with it and detecting the contact between the imprint and the exhibition glass sheet; acquiring by contact at least one image of the imprint after contact with the exhibition glass sheet; and standardizing at least one of the contact-less images in proportions that are identical to those of one of the contact images by analysing at least one of the contact-less images and at least one of the contact images.
